<p>Array of moves to be performed by the user in the current defragmentation pass. </p>
<p>Pointer to an array of <span class="tt">moveCount</span> elements, owned by VMA, created in <a class="el" href="group__group__alloc.html#ga980d7da2ce3b1fd5c8b8476bc362cc00" title="Starts single defragmentation pass.">vmaBeginDefragmentationPass()</a>, destroyed in <a class="el" href="group__group__alloc.html#gaded05a445742a00718ee766144c5c226" title="Ends single defragmentation pass.">vmaEndDefragmentationPass()</a>.</p>
<p>For each element, you should:</p>
<ol type="1">
<li>Create a new buffer/image in the place pointed by VmaDefragmentationMove::dstMemory + VmaDefragmentationMove::dstOffset.</li>
<li>Copy data from the <a class="el" href="struct_vma_defragmentation_move.html#a25aa1bb64efc507a49c6cbc50689f862" title="Allocation that should be moved.">VmaDefragmentationMove::srcAllocation</a> e.g. using <span class="tt">vkCmdCopyBuffer</span>, <span class="tt">vkCmdCopyImage</span>.</li>
<li>Make sure these commands finished executing on the GPU.</li>
<li>Destroy the old buffer/image.</li>
</ol>
<p>Only then you can finish defragmentation pass by calling <a class="el" href="group__group__alloc.html#gaded05a445742a00718ee766144c5c226" title="Ends single defragmentation pass.">vmaEndDefragmentationPass()</a>. After this call, the allocation will point to the new place in memory.</p>
<p>Alternatively, if you cannot move specific allocation, you can set <a class="el" href="struct_vma_defragmentation_move.html#a20996a4686c9246dff77b375ac4a91e2" title="Operation to be performed on the allocation by vmaEndDefragmentationPass().

New place reserved at dstTmpAllocation will be free...">VMA_DEFRAGMENTATION_MOVE_OPERATION_IGNORE</a>.</p>
<p>Alternatively, if you decide you want to completely remove the allocation:</p>
<ol type="1">
<li>Destroy its buffer/image.</li>
<li>Set <a class="el" href="struct_vma_defragmentation_move.html#a20996a4686c9246dff77b375ac4a91e2" title="Operation to be performed on the allocation by vmaEndDefragmentationPass().

</ol>
<p>Then, after <a class="el" href="group__group__alloc.html#gaded05a445742a00718ee766144c5c226" title="Ends single defragmentation pass.">vmaEndDefragmentationPass()</a> the allocation will be freed. </p>
